Ques on B rings

loveshisalis · Sep 2, 2011

Hey ;

If I decide to do the rings on the B, do I need to pull the liners, OR can I hone the liners as is in the block and fit the rings?

they can be honed in place, but they are wet liners, meaning they have o-rings sealing them to the block. IF i had pistons out, i would pull and replace the o-rings.... and clean 60 years of crud out of the water passage after the liners are out.

Hard to decide if you are going to do just rings without measuring the bore and pistons to see if rings will even help. Without measuring the bore and pistons then just honing the bore and putting in new rings could give you less than you already have.

Purchasing a "complete Kit" is best...
You will have all the gaskets, rings, sleeves, Pistons, etc...
You may even be able to increase the compression with a kit designed for that, at the same price..increasing fuel efficiency and Power..

i have done 2-3 "economy" rebuilds on a B motor by buying $60 gasket kit and a $60 ring kit. I get the rings .010 oversize. Take ridge ring off the liners, hone to get them a little straighter and cross hatch. Use the original pistons which are a couple thousands out of spec by now.. then fit the oversize rings to proper clearance. You end up with good compression, no oil burning, and a better motor. I know some will disagree, but if you know what your doing, know what the bore dimension and how far out it is, it will work. AS Dick said, you also have to know the crank and rod sizes and know what your doing on that end. YOu can reshim original bearings to get a couple thousands more tight IF the crank journals are close to round. Again, if you dont know what your doing, you can end up in worse shape than when you started. And i always pull the liners to cleanup and put on new o-rings.

I have done them both way. First tractor engine I ever did was a A/C B and I did not pull the sleeves out and it was fine till the day some friends took it swimming and from that day on it never did run like it should have. Guess A/C-Bs do not like to go swimming in a creek. When I did that one I honed the cylinders put in new main and rod bearings and new rings and it was good to go till that day
